Code:

I've just updated my linux system (Debian) and went to compile some code I'm working on. However it causes some problems, presumable because of GCC up dates. I get many of my subject line errors for example
../../common/Version_Control.cpp: In function int VersionControl():
../../common/Version_Control.cpp:55: warning: deprecated conversion from string constant to char*
So I check up the error and it comes from my error handler code which is a function
extern void SetError(char *string,int error_number)
The net tells me all I need to do is convert char *string to const char *string, however when I do so and recompile I get the following error
Error_Control.cpp: In function �void SetError(const char*, int)�:
Error_Control.cpp:41: error: invalid conversion from �const char*� to �char*�
make: *** [Error_Control.o] Error 1
I think I've done exactly what's recommended ?

My problem is that the warning keeps apperaing when I run g++ compilation.
Say, I have a system runtime function with header (imaginary)sysruntime.h: void printfunction(char *line);
Then in my .cpp file, I will include the above header #include <sysruntime.h>
Then, I do the below:
Line12: char *linetoprint = "Print this line";
Line13: printfunction(linetoprint);
But, I will get the warning message "Line12: deprecated conversion from string constant to 'char*'". (Even though it compiles)
My question is how should I declare my char* so that I wont get this warning message, and can still run printfunction(char* line) correctly?

Code:

I went looking for those files to see if I could symlink a 14 one to either the 15 one or the other ones, but I couldn't find the files anyways. I get this when attempting to run an X windowed program (qmon) and it crashes out while printing the first set of errors.

After upgrading to Lucid I get the following warnings which I did not have before:
Warning: Cannot convert string "-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*" to type FontStruct
Warning: Cannot convert string "-*-helvetica-medium-r-*--*-120-*-*-*-*-iso8859-1" to type FontStruct
These occur when I start emacs and xpdf. On searching I see people are adding font paths to their xorg.conf file but on looking at mine there is no longer a font section. Also I have few directories fonts/X11/usr/share/fonts/X11$ ls misc/util/. I'm assuming the above folders and xorg.conf file are correct.

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.

So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.
